HBD, defined

Creating definitions in the Urban Dictionary, that's what! Hey, it's something, at least. And voting these definitions to the top of their respective entries is something any reader is able to do right now, by going here and clicking on the thumbs-up for what is currently definition #7 [now at #2--keep pushing!], which reads as follows:

An acronym that stands for human biodiversity. It is the acknowledgement and study of how humans differ from each other on both the individual and group levels because of differences in genotype. Differences include, but are not limited to, personality traits, athletic ability, intelligence, height, health, and physical appearance.

"What are some things that HBD informs us on?"

"Why professional sports leagues like the NBA and NFL are dominated by people of West African descent, why blacks and Hispanics consistently perform more poorly on all forms of cognitive testing than whites and Asians do, and why the Amerindian immigrants mowing lawns in the suburbs are so much shorter than the residents of those suburbs, just to name a few."

We propelled NAM to the top in a matter of weeks, displacing the entry specifying the Southeast Asian country. The acronym for "happy birthday" is even more formidable, but I'm confident it's reign at the top is on borrowed time!
